UNIVERSAL PIPE CONNECTER Filed June 17, 1935 Patented June 30, 1936 UNITED STATES PATENT QFFIQE.

Claims.

The object of my invention is to provide a coupler for connecting pipes together or to connect a pipe to a drum, such as a mufiler, whereby a pipe, such as an exhaust pipe, maybe coupled 5 to an internal combustion mufiler or other similar drum-shaped member.

One of the particular objects of my invention is to provide a universal pipe coupling so constructed and assembled as to form a gas-tight connection at the point of interjointure of pipes of the same or different sizes or the point of interjointure of a pipe and a drum-shaped member, such as a muilier, thus enabling the use of the mufller in conjunction with pipes of different diameters and consequently rendering the coupler universal in character.

The coupler of my invention is of particular commercial value in mufiler assembly, since it provides means that enables ready assembly of the mufiier having the coupler in conjunction with engines employing exhaust and tail pipes of different diameters.

The coupler may be manufactured at a minimum cost, and by its use standard mufflers may be used regardless of the diameters of the exhaust and tail pipes, thereby eliminating the necessity of particular mufflers in each variation of exhaust and tail pipe diameter.

The invention consists in other features and advantages which will appear from the following description and upon examination of the drawing. Structures containing the invention may partake of different forms and still embody the invention. To illustrate a practical application of the invention I have selected a coupler as an example of the various structures and details thereof that contain the invention and shall describe the selected coupler hereinafter, it being understood that variations may be made without departing from the spirit of the invention. The particular coupler selected is shown in the drawing and described hereinafter.

Fig. 1 is a perspective view of a mufiler and shows the exhaust and tail pipes coupled to the muffler by means of the universal coupler of my invention. Fig. 2 is a section of the coupler taken on the plane of the line 22 in Fig. 1. Fig. 3 is a perspective view of a flanged locking disc shown in Fig. 2. Fig. 4 illustrates another of the flanged locking discs shown in Fig. 2.

The particular coupler shown in the drawing comprises a cylindrical part within which are located one or more discs having central openings, the diameters of which substantially conform to the diameter of the pipes to be coupled. The coupler also comprises means for wedging edge parts of the disc against the cylindrical part of the coupler and the pipe, as by a collar threaded on the cylindrical part and having a portion for engaging the outer edge of the disc.

Haviland 1935, Serial No. 27,000

In the form of construction shown in the drawing, the universal coupling comprises a cylindrical portion 2 adapted to receive the end of a pipe, such as the exhaust pipe 3 or the tail pipe 4, and a flanged convex locking disc 6 having a central opening 9 approximating the diameter of the pipe, and an abutting part adapted to en gage the edge of the flange H] of the disc. A second similar disc may be used to form the abutting part and at its outer edge abuts a ridge formed in the cylindrical part. The inner edge portions of the discs abut with increasing pressure when their outer edges are drawn toward each other, and such abutment forms a rigid, gas-tight connection between the pipe and the muffier or between two pipes of the same or different diameters. In the form shown, the substantially similar discs 6 and I2 are convex in form and have centrally located flanged openings 9, the diameters of which substantially coincide with the diameter of the exhaust pipe 3 or the tail pipe 4 to be coupled to the muiiler. The flanged portion I3 of the disc I2 is adapted to receive the outer edge of the flange portion ll] of the disc 6 in abutting relation and the flange portion I3 flares at its outer edge as at 5 to increase the wedging action of the flange part I!) against the part IS. The flaring portion serves also to maintain the edge of the flanged part in against the pipe, thereby maintaining the pres sure of the flange against the pipe.

Not only does the outer edge portion of the flange l0 abut and wedge against the flanged portion I3, but the inner surfaces of the flanged portions abut the outer cylindrical surface of the u pipe 3, and it is apparent that an increased pressure at the periphery of the disc 6 results in an increased pressure of abutment of the flanged part I0 against the exterior surface of the pipe, and when the disc I 2 is engaged as against lateral movement with respect to the pipe. such increased pressure at the periphery of the disc 6 operates also to increase the abutment of the flange I3 against the exterior surface of the pipe and also to increase the wedged engagement of the flanged portions l0 and I3.

In the form of construction shown, the cylindrical part 2 is threaded, as at l8, and receives in threaded engagement a collar l9 having an inturned flange or lip portion 20. tion 20 is adapted to engage the periphery of the disc 6 and consequently since the muiiler 5 and the pipe 3 are maintained as against lateral movement with respect to each other, engagement of the disc 6 by the inturned flange 2i! maintains a constant pressure against the periphery of the disc 6 and consequently of the flange I0 against the exterior surface of the pipe 3. This pressure tends to draw the pipe 3 and the muffler toward each other and due to the The lip perimmovability of these mernbers forms a gastight connection between the pipe and muiiler.

It is apparent thatif desired the pipe 3 may be provided with a protruding portion against which the outer edge of the flange it may wedge to form a gas-tight connection. If two discs, such .as thediscs Sand 2,;21'8 employed to form a connection, the cylindrical part is provided with a' bead 22 against which the periphery of the disc I2 is seated; and the flanged portion [3 of the,

disc I2 forms the surfaceagainst which the outer surface of the flange l t wedges to form the abutting relationship between the flange l0 and theiexteriorisurface of the pipe 3. theabead 22 prevents lateral movement of l the disc l2 withrespect to the pipe, the pressure of the nturned flange "2G forces the flanged portion ll] into wedged engagement with the flaringportion l5' of the disc I? and the interier surfaces of theflanges l0 and" H3 against the exterior'surfaces of the pipe 3 to form the gas-tightlseal and connection. 7

When the coupler is assembled, a coupler {is inserted in each end of the muflier drum e'and forms a head. The flange portion 27 of the conpler may be welded in the end of the muffler. Where two discs are employed, the disc l2 'is seated against the bead 22 of the cylindrical part 2, andlthe periphery of the disc 6 is engaged by the inturned" flange of the cellar which is The presadjusted by adjustment of the cpllar through the openings 25; The discs 5 and i2 are formed ofistandard diameters, and the openings 9 may be coupled in the same manner to the mufiler,
